Alright, so I plan on making a gaming computer. I want it to run on both an AMD processor and an AMD graphics card. I need to know what the ABSOLUTE best possible combination would be. It needs to be able to support up to 4k display and have a fast processing speed. I would also like to know how much this is going to cost. The price is not a problem, I imagine this will take a VERY long time for me to build so I'm just going to buy piece by piece until I get my full setup. I would also like to know what type of cooling systems you would recommend. I really wouldn't want a liquid cooling system, I know they're good but I don't really trust it to not leak or anything so just fans and the lot preferrably. Any other parts and components you would like to recommend would also be appreciated. Thanks a lot!

If you wish to achieve absolute maximum performance, you are going to need a very high end Intel i7 cpu (something like i7-4960X), put a Corsair H100 on top of it, then overclock it to 4.5ghz. Then maybe two R9 295x2's (I don't know if its even possible, if not, then 3x R9 290x in trifire).
